JOHN M. KROYER, OF STOCKTON, CALIFORNIA.

TRACTOR-EVHEEL.

- State of California, have invented certain new and useful Improvements in Tractor- \Vheels; and I do declare the following to be a clear, full, and exact description of the vsame, such asnvill enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference'marked thereon; which form a part of this application.

This invention relates to improvements in wheels for general purposes, but is particularly designed for use in' connection with self propelled tractors usingany suitable power.

The object of the invention is to produce a wheel which will have a very effective. traction effect against the ground irrespective of the character of the ground and particularly a wheel which will pull through plowed or other loosened earth without the chance of such earth impeding the progress of the wheel by piling or being pressed up in front of the same which gives to the wheel the effect of continually pulling up-- hill.

My improved wheel is provided with a traction means which causes it to grip firmly on slippery surfaces or on loosened eart surfaces it is designed to continually pass the loose dirt, which is inclined to pile up in front of the wheel, through the body of the wheel, but still not in 5 ch a manner as to prevent the tractive operition of such wheel.

A further object of the invention is to produce. a simple and inexpensive device and yet one which will be exceedingly efi'ective for the purposes for which it is designed.

These objects, I accomplish by'rneans of suchstructure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims."

On the drawings similar characters of reference indicate corresponding parts in theseveral views.

Figure 1 is an end view of one of my 'improved wheels. Fig. 2 is a bottom view of the same. Fig. 3 is a sectional view of a cutter 'rin and supporting arms taken on a line XI% of Fig. 2.

Referring now more particularly to the characters of reference on the drawings, the

numeral 1 designates the hub of the wheel and the numeral 2 the spokes. In Xl'lV improved wheel these spokes 2 are disposed on unc sid e of the wheel and have outwardly pro ect ng arms 3, each arm having .a pair of spaced flanges l. Secured ;to each set of saidflanges l is an independent cutter ring or run 5 consisting of a specially'designed steel casting which comprises the said ring 5 which is beveled on its outer edge to form a cutter, there being a plurality of spaced pro ecting arms 5"- olr'eacli of the rings, said arms being disposed in equal spaced relation with respect toeach other. These cutter rings or rims, as-will therefore he noted, will also constitute the outer supporting rim for the wheel leaving-an interme'diate clear space between said cutter rings, as seen clearly in Fig. 2. -I then provide the tractive means of the wheel which consists principally of a plurality of cast steel angle grips or similar members (i placed. acres the said rings 5 and secured to members 3*. These members 6 may be disposed in a slightly inclined or in any other desired position and are of course spaced apart with relation to each other to form interi'nediate spaces out between themselves and between u, there is a continuous clear space between the cutters 5 and the members 6 and while the projecting edges of the cast steel angle grip form a tractive surface for the wheel, still any loose dirt which would hac a tendency to. pile up in front of and impede the progress 'of a solid wheel would merely work and sift through the spebetween work or sift through the in or e to the ground again through the rear part of the wheel. This operation. would also be materially aided by the cutter via 5 which would cut through the dirt. and I H impede its movement or can thereagainst or between the men e The large and efi'ective tractwe surface given by the projecting parts of cast steel angle grips (3 will cause the same to ground or weedy ground and aid pellingofthe tractor forward with... of power. For traveling on re one point to another wl a smooth band may he bol' cast steel angle grips 6 and then such jections will not cut or injure the roads over which the tractor passes.

From the foregoin description it will be readily seen that I iave produced such a device as substantially fulfills the objects of the invention as set forth herein.

Vhile this specification sets forth in detail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A device of the character described comprising a hub, spokes mounted on one end of said hub, projecting arms on the outer ends of said spokes, a plurality of cutter rings secured to said arms in spaced relation and angle grips secured on said cutter rings in spaced relation, as described.

2. A device of the character described comprising a hub and spokes, spaced cutter rings mounted on said spokes, each cutter ring being provided with a plurality of projecting arms, said arms being disposed in spaced relation, and a plurality of gripping members mounted on said projecting arms, as described.

3. A device of the character described comprising the combination of a hub, spokes mounted on one end of said hub, a projecting arm on each spoke, a pair of spaced flanges on each arm, a cutter ring secured to eaclrof said flanges, said cutter rings being provided with a plurality of spaced arms, and gripping members secured to said spaced zirms, as described."

In testimony whereof I aifix my signature in presence of two witnesses.
